Description

Technical Field

[0001] This invention relates to the fields of vehicle engineering and power management, specifically a power management system for laser bomb disposal vehicles. Background Technology

[0002] As specialized equipment, laser-based bomb disposal vehicles require stable and sufficient power to support their core vehicle-mounted laser and auxiliary systems during operation, ensuring the smooth conduct of bomb disposal work. Currently, the industry primarily relies on mains power or diesel generator sets for the power supply of such vehicle-mounted equipment, directly meeting the equipment's operational needs. This power supply mode has become a relatively fixed technical approach in long-term application and is widely used in power supply scenarios for various high-power vehicle-mounted devices.

[0003] However, existing power supply models have many problems. The lack of a dedicated management system to coordinate and control both upstream power distribution and downstream power output results in cumbersome power supply logic control processes, low overall intelligence, and difficulty in adapting to the flexible power supply needs of complex operational scenarios. In scenarios without mains power, relying on diesel generator sets adds extra requirements for support vehicle configuration or increases the size and weight of the vehicles themselves, severely impacting vehicle mobility and limiting the application scope of laser bomb disposal vehicles. Simultaneously, traditional cooling systems do not employ cold storage design, requiring continuous consumption of large amounts of electrical energy to maintain cooling during equipment operation. This places higher demands on the power supply equipment's power output, further increasing the operational burden on the power supply system. Summary of the Invention

[0004] The purpose of this invention is to provide a power management system for laser bomb disposal vehicles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: comprising a front-end intelligent power distribution management module, a rear-end intelligent power management module, an energy storage battery and its management system, a power take-off generator system, a mains power system, an intelligent distribution box, an intelligent power supply box, a display screen, and a cooling system. The front-end intelligent power distribution management module is used to manage the power supply of the power take-off generator and the mains power, as well as the charging and cold storage processes. The rear-end intelligent power management module is located in the intelligent power supply box, which provides precise power supply to each load through multiple power supply modules and controls the output logic of each power supply. The energy storage battery and its management system are used to store electrical energy and power the vehicle-mounted laser and its auxiliary systems. The display screen is used to display system status parameters.

[0006] As a further preferred embodiment of this technical solution: the power management system adopts a power supply architecture of energy storage battery, power take-off generator or mains power. The power take-off generator can charge the energy storage battery in driving and parking states. When necessary, the energy storage battery and the power take-off generator can simultaneously power the vehicle laser and its auxiliary systems. When mains power is available, mains power can replace the power take-off generator for power supply.

[0007] As a further preferred embodiment of this technical solution: the cooling system is a cold storage cooling system, which can be pre-charged with mains power or a power take-off generator to cool the cold storage tank of the cooling system, and after the charging is completed, it can support the operation of the water cooling system for at least one day;

[0008] As a further preferred embodiment of this technical solution: the intelligent power supply box is equipped with a power management system control board and a signal acquisition board. The signal acquisition board is used to control the devices in the power management system, acquire device status parameters and perform signal conversion. The power management system control board is used to receive signals, implement overvoltage, undervoltage, overcurrent, overload, short circuit and overtemperature protection, and communicate with the vehicle host computer.

[0009] As a further preferred embodiment of this technical solution: after the power management system is powered on, the control system is started, and the system detects whether the energy storage battery is online and whether there is a fault, and whether the signal acquisition board and relay are in normal condition through RS485 communication. After the detection is normal, the battery power assessment stage is entered.

[0010] As a further preferred embodiment of this technical solution: the battery power assessment step determines whether the system is suitable for full power output and estimates the working time based on the output voltage, battery power, and battery health status parameters reported by the energy storage battery.

[0011] As a further preferred embodiment of this technical solution: before the high-power load is turned on, the cooling system is started to pre-cool the high-power load. When the temperature drops to the preset threshold, the green status indicator light on the control panel lights up. During the operation of the high-power load, the cooling system continues to run. Even if the system stops suddenly, it will be delayed for a preset time after the high-power load is turned off before stopping. After the high-power load is turned off, the cooling system continues to cool down to the normal temperature range of the equipment.

[0012] As a further preferred embodiment of this technical solution: the power management system monitors the voltage and current of each output branch of the system in real time, with a monitoring period of 100ms. When the voltage or current exceeds the threshold, overvoltage and overcurrent protection is triggered.

[0013] As a further preferred embodiment of this technical solution: when the system is powered off, it follows a preset power-off sequence, first shutting down each load, and then disconnecting the energy storage battery power supply after detection and confirmation;

[0014] As a further preferred embodiment of this technical solution: the front-end intelligent power distribution management module and the rear-end intelligent power management module achieve collaborative management through communication. The status of all devices is uploaded to the intelligent power box control board, and then uploaded to the vehicle through the host computer communication. The vehicle control commands are sent to the intelligent power box control board through the host computer communication and then executed.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The power management system enables centralized management of both upstream power supply and downstream power distribution, simplifying the overall logic of power supply control, improving the system's intelligent management and control level, and adapting to the power supply needs of complex operating scenarios.

[0017] 2. The power supply architecture combines energy storage batteries with power take-off generators and mains power, eliminating the need for additional support vehicles and avoiding excessive increase in the size and weight of operating vehicles. This effectively improves the mobility of the laser bomb disposal vehicle and broadens its application scenarios.

[0018] 3. The cooling system adopts a cold storage design, which meets the cooling needs during equipment operation by pre-storing cold, greatly reducing the power consumption of the cooling system during operation and reducing the operating burden of the power supply system. The cooling effect can be guaranteed without increasing the power of the power supply equipment. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example

[0025] Please see Figures 1-4 This is a schematic diagram of some embodiments of a power management system for a laser bomb disposal vehicle, as described in this application.

[0026] This embodiment includes a front-end intelligent power distribution management module, a back-end intelligent power management module, an energy storage battery and its management system, a power take-off generator system, a mains power system, an intelligent distribution box, an intelligent power supply box, a display screen, and a cooling system. The front-end intelligent power distribution management module is used to manage the power supply of the power take-off generator and mains power, as well as the charging and cold storage processes. The back-end intelligent power management module is located in the intelligent power supply box and provides precise power supply to each load through multiple power supply modules and controls the output logic of each power supply. The energy storage battery and its management system are used to store electrical energy and power the vehicle-mounted laser and its auxiliary systems. The display screen is used to display system status parameters.

[0027] It should be noted that the power management system of this invention is specifically designed for laser bomb disposal vehicles. Its core function is to solve the power supply and distribution problems of the vehicle-mounted laser and its auxiliary systems, achieving system lightweighting and improving vehicle mobility while ensuring sufficient continuous working time. The system mainly consists of a front-end intelligent power distribution management module, a rear-end intelligent power management module, an energy storage battery and its management system, a power take-off generator system, a mains power system, an intelligent distribution box, an intelligent power supply box, a display screen, and a cold storage cooling system (including a cold storage pack). All components work collaboratively through pre-set circuits and communication links.

[0028] The intelligent power distribution box, as the core execution component of the front-end intelligent power distribution management module, connects to the power take-off generator system, the mains power system, the energy storage battery and its management system, and the cooling system. It is responsible for the power distribution logic management of power supply to the power take-off generator, mains power supply, energy storage battery charging, and cooling system cold storage power supply. The intelligent power box has a built-in back-end intelligent power management module, which integrates a power management system control board, a signal acquisition board, and multiple independent power supply modules. After obtaining power from the bus, the power supply modules provide precisely matched power supplies to various loads such as vehicle-mounted lasers and auxiliary control equipment. The display screen communicates with the power management system control board of the intelligent power box to display various status parameters such as system power supply status, battery parameters, and equipment fault information in real time. The energy storage battery and its management system are used for energy storage and output control, and can switch between charging and discharging according to power demand.

[0029] In this embodiment, the power management system adopts a power supply architecture of energy storage battery, power take-off generator or mains power. The power take-off generator can charge the energy storage battery in driving and parking states. When necessary, the energy storage battery and the power take-off generator can simultaneously power the vehicle laser and its auxiliary systems. When mains power is available, mains power can replace the power take-off generator for power supply.

[0030] As a preferred implementation method, this system adopts a hybrid power supply architecture consisting of energy storage batteries, power take-off generators, or mains power. The specific operating modes are as follows:

[0031] Mains power availability scenarios: When the laser bomb disposal vehicle is in a location with mains power supply (such as a garage or work preparation area), the mains power is connected to the system through the intelligent power distribution box. On the one hand, it can directly power the vehicle-mounted laser and its auxiliary systems. On the other hand, it can simultaneously charge the energy storage battery and perform pre-charging and cooling operations on the cooling system's cold storage pack. After the cooling is completed, the cold storage pack can support the water cooling system to work continuously for at least one day, effectively reducing the power consumption of the cooling system during subsequent operations.

[0032] In scenarios where there is no mains power and the energy storage battery has sufficient charge: When the bomb disposal vehicle is in an environment without mains power and the energy storage battery has sufficient charge, the energy storage battery and its management system can supply power to the vehicle laser and its auxiliary systems independently, without the need to start the power take-off generator, thus achieving lightweight operation of the system and improving mobility.

[0033] In scenarios where there is no mains power and the energy storage battery is low on charge: the power take-off generator system is activated. The power take-off generator can work in driving or parked mode, directly powering the vehicle laser and its auxiliary systems on one hand, and charging the energy storage battery on the other. In special circumstances such as continuous operation of high-power loads, the energy storage battery and the power take-off generator can supply power simultaneously to ensure power supply stability and duration.

[0034] Specifically, the cooling system is a cold storage cooling system, which can be pre-charged with mains power or a power take-off generator to cool the cold storage tank of the cooling system. After the charging is completed, it can support the operation of the water cooling system for at least one day.

[0035] In this embodiment, the intelligent power supply box is equipped with a power management system control board and a signal acquisition board. The signal acquisition board is used to control the devices in the power management system, collect device status parameters and perform signal conversion. The power management system control board is used to receive signals, implement overvoltage, undervoltage, overcurrent, overload, short circuit and overtemperature protection, and communicate with the vehicle host computer.

[0036] Specifically, after the power management system is powered on, it starts the control system and uses RS485 communication to detect whether the energy storage battery is online and whether there is a fault, and whether the signal acquisition board and relay are in normal condition. If no abnormalities are detected, it enters the battery power assessment stage.

[0037] In this embodiment, the battery power assessment step determines whether the system is suitable for full power output and estimates the working time based on the output voltage, battery power, and battery health status parameters reported by the energy storage battery.

[0038] Specifically, the cooling system is started before the high-power load is turned on to pre-cool the high-power load. When the temperature drops to the preset threshold, the green status indicator light on the control panel will light up. The cooling system continues to run during the operation of the high-power load. Even if the system stops suddenly, it will be delayed for a preset time after the high-power load is turned off before stopping. After the high-power load is turned off, the cooling system continues to cool down to the normal temperature range of the equipment.

[0039] In this embodiment, the power management system monitors the voltage and current of each output branch of the system in real time with a monitoring period of 100ms. When the voltage or current exceeds the threshold, overvoltage and overcurrent protection are triggered.

[0040] Specifically, the power management system monitors the voltage and current of each output branch of the system in real time with a monitoring cycle of 100ms. When the voltage or current exceeds the threshold, overvoltage and overcurrent protection are triggered.

[0041] In this embodiment, the front-end intelligent power distribution management module and the back-end intelligent power management module achieve collaborative management through communication. The status of all devices is uploaded to the intelligent power box control board, and then uploaded to the vehicle through upper computer communication. The vehicle control commands are sent to the intelligent power box control board through upper computer communication and then executed.

[0042] After the power management system is powered on, the control system starts immediately. It establishes an RS485 communication connection with the energy storage battery and its management system via the signal acquisition board. First, it checks if the energy storage battery is online, and simultaneously collects parameters such as the individual battery cell voltage and output current to determine if there are any faults, such as a cell voltage below 2.7V or an output current exceeding a threshold. If a fault is detected, the signal acquisition board converts the fault signal and transmits it to the power management system control board, which then reports the specific fault type on the display screen. If the energy storage battery is not faulty, the control system continues to check the status of its own relays and the connection status of each power supply branch via the signal acquisition board. Once all equipment statuses are normal, it proceeds to the battery power assessment stage.

[0043] During the battery power assessment phase, the power management system control board receives parameters such as output voltage, remaining power, and battery health status reported by the energy storage battery and its management system. Combined with preset high-power load power demand thresholds, it determines whether the current battery status is suitable for full-power output. Based on the remaining power and load power, it estimates the system's sustainable operating time, displaying the estimation results in real-time on the screen for operator reference. If the battery status does not meet the full-power output requirements, the control system will limit the load output power or prompt the generator to be started to supplement power.

[0044] Before starting high-power loads such as vehicle-mounted lasers, operators manually activate the cooling system. This system utilizes pre-stored cooling capacity from a cold storage tank to pre-cool the high-power load. The power management system monitors the load temperature in real-time via a signal acquisition board. When the temperature drops to a preset threshold, a green indicator light on the control panel illuminates, indicating that the high-power load can be started. During high-power load operation, the cooling system continues to run. Even if the system triggers an emergency stop command, the high-power load must be shut down first, and the cooling system should only be shut down after a preset delay (3-5 minutes depending on the actual operating conditions). After the high-power load is normally shut down, the cooling system continues to run to cool the equipment until the temperature drops to room temperature, at which point the operator manually shuts down the cooling system. Throughout the entire process, the power management system monitors the power supply status of the cooling system in real-time to ensure its stable operation.

[0045] During system operation, the power management system control board monitors the voltage and current of each output branch in real time through the signal acquisition board, with a monitoring cycle set to 100ms. When the voltage exceeds the overvoltage threshold, the current exceeds the overcurrent threshold, or abnormal conditions such as overload, short circuit, or overtemperature occur, the power management system control board immediately triggers the corresponding protection mechanism, cuts off the corresponding power supply branch, and reports the abnormal information on the display screen to prevent equipment damage.

[0046] When the system is powered down, it follows a preset power-off sequence: after the operator issues a power-off command, the power management system control board first controls each load to shut down in sequence. After the signal acquisition board detects and confirms that all loads have stopped normally, it sends a power-off command to the energy storage battery and its management system to disconnect the battery power supply circuit and complete the entire power-off process.

[0047] The front-end intelligent power distribution management module and the rear-end intelligent power management module work together through an internal communication link. The working status and power supply parameters of all devices are uploaded to the control board of the intelligent power box through the signal acquisition board. The control board then uploads the information to the vehicle control system of the laser bomb disposal vehicle through the host computer communication interface. Conversely, the control commands of the vehicle control system are also sent to the control board of the intelligent power box through the host computer communication interface. The control board controls the front-end power distribution logic and the rear-end power output according to the commands, realizing the coordinated control of the system and the vehicle.

[0048] Working Principle: The power management system of this invention achieves precise power supply and distribution control for the vehicle-mounted laser and its auxiliary systems in laser bomb disposal vehicles through the collaborative work of the front-end intelligent power distribution management module and the rear-end intelligent power management module. The system connects to three power sources: a power take-off generator, mains power, and energy storage batteries. The front-end intelligent power distribution management module is responsible for the rational allocation of various power sources, including charging the energy storage battery, cooling the cooling system's cold storage pack, and directly supplying power to the load. The rear-end intelligent power management module, through multiple built-in power supply modules, provides suitable power supplies for different loads and controls the power output logic according to load requirements.

[0049] After power-on, the system first activates the control system, which uses the communication link to detect the status of devices such as the energy storage battery, signal acquisition board, and relays. Once the system confirms there are no faults, it assesses the battery charge and health status to determine suitability for load operation. Before starting a high-power load, the cooling system is run for pre-cooling. The load is started only after the temperature conditions are met. During load operation, the cooling system continues to operate until the load is shut down and the equipment cools to room temperature. The system monitors the operating status of each power supply branch in real time during operation. In case of abnormalities, the protection mechanism is immediately triggered. Upon power-off, the system follows the sequence of first shutting down the load, then disconnecting the battery power supply. Simultaneously, all system status information is exchanged in real time with the vehicle control system, receiving vehicle commands and feeding back operating parameters.
